Definitions

  • This invention relates to watches provided with calendar mechanism that is which are arranged to show the number of the day of the month and the name of the day of the week, and has for its object to provide improved means whereby the calendar mechanism can be readily set to the correct number and name.
  • the number and name disks carrying respectively the numbers 1 to 31 and the names of the seven days of the week are operated by two wheels adapted to rotate about the same axis, one wheel having thirty-one teeth and being connected to the number disk and the other wheel having seven teeth and being connected to the name disk. Each of these wheels is rotated through one tooth every twenty-four hours in the usual manner.
  • the so called number disk and wheel are only arranged for a month of thirty-one days it is necessary that for short months after the number of the last day the number 1 shall appear for the first day of the following month, the number 31 and in February the numbers, 29, 30 and 31 being passed over. It is furthermore necessary that the calendar mechanism may in consequence of the watch stopping or keep ing incorrect time, be at any time set to the actual date and that the number and name of the day may be brought to agree.
  • the setting or adjustment of the number and name disks is effected by the regulator 0 provided with four arms; one arm extends to the outside of the watch case through a small slot in the case and serves to operate the regulator; another arm 0 forms a spring firmly held at its free end between two stops and tends to force the regulator to its neutral or central position; a third arms is adapted when the operating arm is moved to the left to engage with a tooth of the number wheel a and retate it through one tooth, and when the operating arm of the regulator is released the regulator is returned by the spring arm 0 to its normal position out of gear with the wheel a and can be again operated if desired to move the wheel a forward another tooth and so on; the fourth arm 0 acts in a similar manner on the name wheel I) to move it backward when the operating arm of the regulator is moved to the right.
  • a regulator for calendar mechanisms of watches provided with an external operating arm, with a spring arm always tending to forceit to its central or neutral position and with two pawl arms, one adapted when the operating arm is moved in one direction to rotate the number wheel and the other adapted when the operating arm is moved in the other direction to rotate the name wheel in each case the space of one tooth from the position previously occupied the whole substantially as described for the purpose specified.
  • testi mony whereof I have aifixed my signature in presence of two witnesses.
